An embodiment of the current invention is directed to retaining customers for a wireless-service provider (“carrier”). A plurality of users who are influencers are identified from a group of wireless-service subscribers, wherein an influencer is a user who is likely to affect decisions of other users regarding whether to cancel or maintain their subscriptions with a particular carrier based on whether the influencer cancels or maintains his or her subscription. A list of influencers is thereby created. An incentive to provide the list of identified influencers is determined. The incentive increases the likelihood that the set of influencers will retain their respective subscriptions, thereby increasing the likelihood that other subscribers who might be influenced will also retain their respective subscriptions.
